Automotive Buck-Boost Pmic W/5 Ldo Outputs ARG81400KLVATR
The ARG81400 is rated up to 50V input and provides 6 total outputs. There are 5 LDOs, and a post regulated DC/DC switcher to power MCUs, as well as a watchdog, and SPI. Designed for high-temperature operation, the ARG81400 is ideal for Automotive and Industrial applications. The device uses a buck or buck/boost pre-regulator to efficiently feed five linear regulators— 3.3 V / 90 mA, 5 V / 200 mA, 5 V / 30 mA, 5 V / 55 mA, and 5 V /100 mA (short-battery protected)—and an adjustable output, 600 mA synchronous buck. Diagnostic outputs from the ARG81400 include a power-onreset output (NPOR), and a fault flag output to alert the microprocessor that a fault has occurred. The microprocessor can read fault status through SPI. The ARG81400 contains a Window Watchdog timer with a programmable detect period. It enters an active state after NPOR transitions high and the processor has exercised the WD Test routine. The watchdog can be put into flash mode or be reset via secure SPI commands Protection features include undervoltage and overvoltage on all output rails. In case of a shorted output, all linear regulators feature foldback overcurrent protection. In addition, the V5P output is protected from a short-to-battery event. Both switching regulators include pulse-by-pulse current limit, hiccup mode short-circuit protection, LX short-circuit protection, and thermal shutdown.
